if 25 : 35 : : 45 : x​

Answer 1

ANSWER :-

X = 63

STEP BY STEP EXPLANATION :-

IF 25:35 :: 45 :X

So ,

X will be :-

25 /35 = 45 / x

=> 25x = 45×35

=> 25x = 1575

=> x = 1575 /25

=> x = 63

Answer 2

Answer:

Value of $x$ is $63$ .

Step-by-step explanation:

To find : value of $x$

Given ratio : $25 : 35::45:x$

Solution:

• As we can see that in the given ratio of proportion ' $x$ ' is missing.
• In the given ratio of proportion, $25 : 35::45:x$  , $35$ and $45$ are called as means while $25$  and $x$ are called as extremes.
• We know that, product of means = product if extremes.
• Substituting values in above formula to find the value of $x$.
• $35\times 45 = 25\times x$

             $1575= 25x \\\\x =\frac{1575}{25} \\\\x = 63$

Note :

Question for above solution is :

Find the value of $x$ in the given ratio of proportion,  $25 : 35::45:x$ .
